Abstract
Fri'tsche.a. N.L. fem. n.
Fritschea
named after Thomas R. Fritsche, an American physician and parasitologist, in honor of his contributions to our current knowledge on chlamydial diversity.
Coccoid to rod‐shaped, nonmotile, obligately intracellular bacteria, up to 2.5 μm in length
. Cells show a
developmental cycle
with morphologically distinct stages similar to those of the
Chlamydiaceae
. Organisms were found in whitefly and scale insects, but have not yet been obtained in cell culture. The genus is based on the description of “
Candidatus
Fritschea bemisiae” and “
Candidatus
Fritschea eriococci” (Everett et al., 2005; Thao et al., 2003) (Figure 1).
